Hi,
Have managed to find some Z time in the last day or two.
I decided to replace the diff mount, that lead to removing the rear wheels and discovering a leaking wheel cylinder.
Easy enough, available from the local auto shop - problem solved (already had a set of linings)
While the diff was out ripped the back cover off and yep 39/11 = 3.54. That explains the less than spirited acceleration !
Decided I would take my time and start looking for 39/10 = 3.9 R180 diff over the next couple of weeks. While I was collcting the exhaust manifold today we got chatting about the project. I mentioned the 3.54 diff and the plan to look for a 3.9. My lucky day, headed home with not only the much needed manifold but also an R180 @ 3.9 on loan to see if I like the ratio.
So I now have some work ahead me for the rest of the week.
Clean and reassemble rear brakes
Fit inlet & Exhaust Manifolds
Fit 3.9 diff
All in all a good few days in my Z journey
Cheers
Pb
